Application filed May 18, 1910. Serial No. 561,932.

all whom it may concern: e it known that I, WALTER l'lonsen, 'a tlzenof the United States, residing at in the county of Carbon and tain new and useful Improvements in Automatic Valves for Steam and Hot-Water Ra diators, of which the following is a spec1fication.

My invention relates to improvements 1n automatic valves for steam and hot water radiators, and more particularly for use in "connection with my improved heating system, set forth in my application for Letters Patent executed on even date therewith, the object of the invention being to provide an automatic valve which will insure a uniform temperature in the radiator, and which Wlll allow the water of condensation. and gases in the radiator to-escape.

A further object is to provide an 1111- provedautomatic valve of this character, which may be, attached to any ordmary radiator atthe outlet end thereof, and which will automatically control the temperature of the radiator, and which will be simple, inexpensive construction, strong and durable infuse.

With these and other objects-in view, the invention consists in certain novel features of construction and combinations and an rangements of parts as will be more fully hereinafter described and'point-ed out in the claims. In the accompanying drawings: Figure 1, is a view illustrating the application of my Fig. 2, is a View in section illustrating my improved au- Fig. 3, is a broken view in longitudinal section of the U- 4, isa view in side levation of Fig. 3. Fag. 5, is a fragmentary showing thelower bifurcated end of strip 27, and l i g. 6, is an en larger. view in vertical section through the 1, represents a, radiator, water supply pipe, 3 a valve'eontrollin the inlet to the radiator, and-4 my improve automatic valve connected at the outlet of-th-e piped fromthe radiatoris con- 'onthe base'portion 9 o e se: i r T is has tion 9 has an externally screw-threaded up per end 'on which a cylindrical casing 10 is screwed, and the lower end of said base has a nipple 11 connected to return pipe 5 by means of a union 12.

A tubular valve seat 13 is screwed into pi 3e 8, and has a beveled end with which a in yo 14 contacts. This valve 14 is secured upon a rod 15, one end ofsaid rod being cured in a sliding guide 16, mounted to slide in pipe 8, and the other end provided with a disk or guide 17, mounted to move in a cylinclosed at its outer end by a IGIl'IO v'HblO plug 19, as shown.

An upwardly projecting U shaped frame 20 is provided on the base 9 and inclosed in cylinder 10, and to the upper end of said frame my improved thermostatic fork 21 is secured bya pivot-pin 2:2. This thermostatic fork comprises a plug 23, to opposite sides of which, compound bars 2 1 and 25 are secured. These compound bars each of extremely I 2 a steam or hot.

consist of strips of two metals, for example, steel and brass. The steel being at 26 and the brass at 27. One member of (lrical guide 18* integral with base 9, and

illustrated this fork is engaged by a set screw 28 so as to regulate the position of the fork to cure its proper operation. The other mem-- ber of this fork is engaged by a flat spring 29, secured to frame 20,. so as to assist in holding the fork in proper position. This member of the fork, which is engaged by spring 29, has its brass strip longer than the steel'strip,and the brass strip at its free end is bifurcated, straddles rod 15, and is located between two disks or shoulders 30 on the rod, so that the movement of .this member of the fork will -move the valve. Due to the. difference in the expansion of the two metals constituting-the members of the an integral -pipe or,

pe t fis'automatical-ly on pe h to.

metals will cause it to asfork, when the temperature in the valve tlnead cd boss 32 around the same, in which a tabular receptacle is screwed. This tubular receptacle 33 is adapted to catch the mud and sediment and may be removed from time to time and cleaned.

Various slight changes might be made in the general form and arrangement of parts described Without; departing from my 'inrention, and hence I do not limit myself to the precise details set forth, but consider my self at liberty to make such changes and alterations as fairly fall within the spiritand scope of the appended claims Havingth-us described my invei'ition, what I claim a'snew and desire to secure by Let'-..

- 'ters Patent is 1. In a device of the character described, the-combination Witli a casing, a valve in said casing, and a rod secured to} thevalve 'and guided in the casing, of a thermostatic. fork, a frarnein saidoasing sup orting said fork,*'one' member of said 015; engaging said rod, a.- spri ng bearing against said meniber engaging the rod, and a set screw engagingftheother member of said fork, substariti'ally as described.

:2. In .a device of the character described,

"the'eom'binationwith a casing, a valve in asaid casin and a rod a tubular extension th secured to the valve and guided in the casing, of a thermostatic fork,'a frame in said'casing supporting said fork, one member of said fork engaging said rod, a set screw engaging the other member of said fork, and each member of said for: comprising two strips of different metals rigidly secured together, substantially as described.

3. In a device of the character described,- the combination with a hollow base having in the end of said tube, a

ereon, of aremovable seat in said tube, a valve adapted ez'igag'e the seat, a rod swarmed to the valve, a guide on said rod movable in the tube. said rod, a tubular guide in satin which said disk projects, a re. in the end o'l. said tube, a ser- --t.ln:oaded opening in said Iiz'st-mentioned t be,'a dopending tubular receptni-le SOCHIGtl in said. opening, a casing on said base, and. a the mostatie :t'ork mounted in said casing and ei'ig'aging said rod, snbstan... scribed.
